Operator: Save these instructions for future use!
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
This wall-mounted, low voltage thermostat maintains
room temperature by controlling the operation of multistage systems. Use this thermostat for applications requiring up to three stages of heat and up to two stages of
cool. Indicator lights show the system status. The user
may program up to four time and two temperature settings
per 24 hour period and may program each day independently. The thermostat will store both heating and cooling
programs simultaneously. A 9 volt Energizer® battery will
maintain the stored program for approximately one week,
if incoming power should fail. If power failure is extensive
and the program is lost, after power restoration, the
thermostat will automatically maintain a factory
preprogrammed heating temperature of 64°F or a cooling
temperature of 82°F.

INST ALLA TION INSTRUCTIONS
DESCRIPTION
PRECAUTIONS
If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
Do not exceed the specification ratings.

Troubleshooting
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting components could cause the control to malfunction.
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electric power to system,at
main fuse or circuit breaker box until installation
is complete.
Do not use on circuits exceeding specified voltage. Higher voltage will damage control and
could cause shock or fire hazard.
Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will
burn out heat anticipator and could cause personal injury and/or property damage.

ATTACHING ON SUBBASE. SEE OPERATION GUIDE
FOR PROGRAMMING INSTRUCTIONS.
Select Thermostat Location
Proper location insures that the thermostat will provide a
comfortable building temperature. Observe the following
general rules when selecting a location:
1. Locate thermostat about 5 ft. above the floor.
2. Install thermostat on a partitioning wall, not on an
outside wall.
3. Never expose thermostat to direct light from lamps,
sun, fireplaces or any temperature radiating equipment.
4. Avoid locations close to windows, adjoining outside
walls, or doors that lead outside.
5. Avoid locations close to air registers or in the direct
path of air from them.
6. Make sure there are no pipes or duct work in that part
of the wall chosen for the thermostat location.
7. Never locate thermostat in a room that is normally
warmer or cooler than the rest of the building.
8. Avoid locations with poor air circulation, such as
behind doors or in alcoves.

1. Probe for obstructions in partition before drilling 1⁄2”
hole in wall at selected location. Take up quarter
round and drill a small guide hole for sighting (see fig.
1). From basement, drill 3⁄4” hole in partition floor next
to guide hole. In houses without basements, drill 1⁄2”
hole through ceiling and into partition from above (see
fig. 1).
2. Through this hole drop a light chain, or 6” chain
attached to a strong cord. Snag cord in basement with
hooked wire. In houses without basements, drop cord
through hole in ceiling and down partitioning; snag
cord at the thermostat location.
3. Attach thermostat wire to cord and pull wire through
hole in wall so that 6” of wire protrudes.

REPLACEMENT INST ALLA TION
Remove Old Thermostat
1. Shut off electricity at the main fuse box until installation is complete. Verify power is off with a voltmeter.
2. Remove the front cover of the old thermostat. With
wires still attached, remove wall plate from the wall.
3. If the old thermostat has a wall mounting plate,
remove the thermostat and the wall mounting plate as
an assembly.
4. Use the Cross Reference Guide to find the thermostat
type you are replacing.
5. Identify each wire attached to the old thermostat
using the labels enclosed with the new thermostat. Record the identification of the wire on the
corresponding blank in Table 1.
6. Disconnect the wires from old thermostat one at a
time. Pull at least 6 inches of wire out of the wall. DO
NOT LET WIRES FALL BACK INTO THE WALL.
7. Install new thermostat using the following procedures.
Attach Subbase To Wall
1. Remove the packing material from the thermostat.
Place the fingers of one hand on the center top and
bottom portion of the thermostat. Grasp the subbase
in the other hand on the top and bottom center, and
gently pull straight out (see fig. 2). The thermostat has
pin and socket connectors. Forcing or prying on the
thermostat will cause damage to the unit.
NOTE
THIS THERMOSTAT REQUIRES BOTH THE HOT
AND COMMON SIDES OF THE 24 VAC TRANSFORMER TO BE PRESENT TO THE THERMOSTAT
FOR OPERATION.

Figure 3. Subbase
2. Connect wires beneath terminal screws on subbase
using wiring schematic for your particular application
(see figs. 3 through 6).
3. Place subbase over hole in wall and mark mounting
hole locations on wall using subbase as a template.
4. Move subbase out of the way. Drill mounting holes.
5. Fasten subbase loosely to wall, as shown in fig. 3,
using two mounting screws. Place a level against
bottom of subbase, adjust until level, and then tighten
screws. (Leveling is for appearance only and will not
